This page is a summary of all the patterned versions of part 58148 (~Electric Power Functions Infrared Receiver Bottom). The background colour indicates the part status :

Reserved - code reserved for a part in development

Obsoleted - code not available for administrative reasons

58148

The range assignments, shown as subheadings, are designed to group together related patterns for
parts with many patterned versions. The rigour with which these have been applied has increased as
more patterned parts have been authored. Code asignment in the early days of LDraw was more haphazard.
For backward compatibility, older patterned parts with codes that do not match the current usage have not
been re-numbered.
